Abstract
Against the backdrop of remarkable strides in recent EUVL research, EUV chemically amplified resists were discussed as a critical issue in last year's International EUVL Symposium. Important concerns involving resists include improvements in resolution and sensitivity and reductions in outgassing and roughness. One important factor in improving resolution and sensitivity is understanding the behavior of the de-protection reaction of a photoresist during EUV exposures. We examined a system to analyze de-protection reactions in an ultra-thin-film process suitable for the EUV resist process.
